Oracle Cloud Infrastructure Architect Associate case studies
OCI Architect Associate · Put your knowledge to work in context.
The Oracle Cloud Infrastructure Architect Associate credential is aimed at cloud and infrastructure engineers who design and operate solutions on OCI rather than simply administering a single service. It sits between foundational cloud knowledge and professional-level architecture work: you are expected to reason about tenancy structure, network topology, compute sizing, storage selection, database placement, resilience, and cost. The OCI Architect Associate case studies are 5 cases and about 5,493 words.
